HAT-,VENTILATION MEANS.

Specification of Letters Patent.

Patented May 4, 1920.

Application led- September 23, 1918. Serial No. 255,400.

To all whom t may concern.'

Be it known that I, WILLIAM HENRY BAUERT, a subject of the King of Great Britain and Ireland, etc., residing at Shirley Road, Roseville, in the State ofNew South Va-les, Commonwealth of Australia, have invented certain new and useful Improvements in Hat-Ventilation Means; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Devices have been used to promote ventilation in hard hats-asthe helmet, bowler, and some of straw-and soft ones-as alpines, other felts, and caps, but such devices are uncomfortably rigid, or they fail to permanently supply ample space for the passage of air up and down between the wearer-s head and the hat side into the space over the top of the head.

My invention is for soft hats chieiy because-to most people no stiff hat is comfortable, especially in hot weather, and more especially when such persons perspire; and because vI aim at uniting comfort with health by providing really permanent and ample air space to allow the air to pass up the hat side to reach the space over the wearers crown and to allow air from the latter space to pass down, so that thel air in that space will be kept fresh. Small holes spaced apart in Ya hat are useless for the purpose stated.

I provide according to the construction I prefer, an attachment or attachments .inside the hat, with one or more leather, textile or other pliable sweat bands the softness, moisture absorbent qualities, and 'general smoothness of such a band being excellent features. Butas the commonly used sweat band becomes insanitary with perspiration, dust, and sometimes grease, before the hat is discarded, and as it is usually so sewn in that it cannot be readily changed by the wearer for a clean one I provide means whereby the said change will be easy.

I use one or more 'flexible resilient or springy corrugated or other strips, of any suitablecross section and -material or combination of materials, such as metal, celluloid, composition or so on,`plain or having a covering as of textile.

If bare metal is used it will be sufficiently rust proof to withstand perspiration and damp.

Each strip or series of strips is shaped in curved form to fit inside the curve of the hat side as a sweat band fits, and is also bent or curved to have an outer and an inner side, these sides being spaced well apart to leave` ample room between them for upward and downward passage of air.

When the material of the strip is not of round cross section it might be called a ribbon but as the materialrused will be in most cases light wire of round crosssection I will in this specification call all the said springy strip material which Vprovides the said air spaces, wire.

Owing to its flexibility and resilience my wire when inthe hat will afford a comfortable t, and it will be able to expand somewhat under verymoderate internal pressure and thus could lit heads which differed a little in size. Y Y Y Y The above and other details of the invention will now be described with reference to the accompanying drawings, which are diagrammatic. Although flat leather sweat bands are illustrated other current styles are usable. In the drawings Figure 1 is a sectional view through the side of the hat, to which is attached one form of my wire attachment with a sweat band as of leather added. The dotted line represents part of the wearers head, and arrows show where air can pass `freely up and down between that line and the inside of the hat. Fig. 2 is a sectional view through a hat side with an attached housing or keeper for tips or other partsof a wire or wires of the kinds shown for example in Fig. 6.

F ig.'3 shows an'end section of a ventilating wire modified so as to have a leather sweat band or the like at each side, so that when the band on the head side becomes soiled the fitting shown may be reversed in position to bring the clean band next to the head. Fig. 4 is a' section through the form of the device shown in Fig. 2, with the spring in place, and sweat band secured to the spring. Fig. 5 is a view of part of a hat side from within with parts of a leather sweat band and between 'it and the hat a ventilating wire attached. Fig. 6 is on a smaller scale and shows a hat under side with various arrangements of my fittings. In these views 1 is the hat crown outer side, 2 the hat brim,

3 its ribbon, lV part of the wearers head, 5 a housing for one or more of my ventilating wiresv (to.r holdA in place their ends` or an intermediate part of any such wire) and 58L is any means connecting the hou-sing to the hat. 6 is any means connecting to the hat the Ventilation wire 7 and 8, 8a indicate absorbent flexible sweat bands. 7a is one of the modified forms of: the Ventilating wire-obviously usable, and 9 and 1l are air* spacesofample'width between the inner (or head) and the outer (or hat) sides of the'v Ventilating' wire. l() is the; space in housing- 5to receive and locatethe ends of adjoining- Ventilating wires, or to locate an intermediate part of any one wire, and 12 is any' suitable connection to-be used begweenza sweat band 8 and aventilatingwire or a.

@ne Ventilating wire 7, may extend all around the hat'side inner surface-13. Ifits ends be not socketed in a housing, they are connectedl in any other suitable manner for example as endsofj spring wire in armlets are connected;

ln my preferred construction 'a plurality offhousings are attachedv to the'hat surface 13 so'that myrventilating wire' orseries 'of wires, canbe attached'or be removed withoutany' trouble: rllhere'isin some 'cases a top and a bottom'wire l5y running around like a ring inside the Ventilating wireff-or,g wires andfadapted to' 'be sewn'or attached to the hat side; Even' when the: connectionV is by sewingthe stitches do,v not need to bei all around part '131b`ut at intervals only, Aso that the' labor` ofJ renovation isi reduced.

In the-- example in'Fig. 5, `downward and upward extensions-of the wire are'L oblique, but'fthe shapings; off the wirel may be :varied while: retaining statedfadvantages; A'n absorbent band is-Ishown atkv 8b in Fig; 6 on the headside of the Ventilating. wire', another band,` at 8"isishown laced'in andV out of the wire.v And. at 8l aband isy shown'loca-ted Wholly inside the-1 airfspace-S), without filling that space.

When pluralityy ofV Ventilating wires is used to form afcircuit'therer will be in some cases: gaps 14- between their ends.`

The air` space. 9,'v 11` orV the like-will di`- minish. to' some`l extent: readily when pressure is'pfutaonxthe leatherfsweat band orv on the Ventilating wiresV or: wires' in' the. use of the hat, but it-'will'benimpossibleby any nornralpressurei'toobl'iterate the space 9 pro vrdedfforair passage or to so reduce it as to destroy thefefliciencyclaimed forthis -invention.: Itawillzbe impossibleforthe head of thez-wearerf to vcomefso close to lsurface 13 thataample fresh air is prevented? from ris;

ing or heated air is prevented from descending between the sweat band and the wall of the hat.

If there be holes in the upper partof the hat crown rair will also escape 'through them. The Ventilating wire or wires will accommodate themselves to the shape of the wearers head, and though they will in many cases under continued wear take a shape more closely fitting the wearers head than originally, other more temporaryV stresseson the wires` will not preventthe normaler correct shape-being regainedby the Ventilating wire when `such stresses 4are removed.

In practice the parts used willv have'any suitable dimensions but in my preferred construction the leatheror absorbent? sweat band extends a little' higher and a little lower than the Ventilating wireforwires.

Having described' this invention: what is claimed by Letters Patent is l. The combination with thev crown of a hat, of a housing secured therein and eX- tending thereabout and having an vapproximate 'U-shape in cross-section,lsaid housing having its edges bent to provide inwardly projecting overhanging flanges, aV hollow ventilator spring having spaced side members providing, .an air spaceV therebetween, saidspringbeingfremovably mounted in the housing, andan absorbent member secured to the inner side'of the springi 2. The eombinationwith the crownvof a hat, of ahousing secured therein and-extending thereabout and having its edges bent-into U-shaped flanges, there being a space between the ends of the flanges which is arranged innermost, a hollow ventilator spring having spacedside members providing an air space therebetween, said spring being removably* mountedy inV the housing and adapted to be passed throughvsaidspace', upper andlower wires arranged within the hollow' Ventilator spring, and an absorbent member secured to the inner side'rof the spring.
